Abstract/ Executive Summary:

It appears that irrespective of mutants and check variety, leaf number, individual bulb weight and diameter, fresh and dry bulb weights and yield were significantly higher at Ishurdi than Rangpur. At Rangpur, only the mutant BP₂/100/1 had significantly higher number of leaf plant^-1 than the check variety BARI Piaj-3. In contrast, at Ishurdi three mutants, BP₂/75/2, BP₂/100/2 and BP₂/100/12 had significantly higher number of leaf than the check variety with BP2/100/12 being the highest followed by BP/75/2. At Rangpur, all the mutants had significantly larger bulb diameter than check variety with BP2/75/2 being the largest while at Ishurdi BP2/75/2 and BP2/100/12 being the largest. Individual bulb weight was significantly higher in BP2/72/2 and BP2/100/2 than the check variety at Rangpur while at Ishurdi three mutants had significantly higher individual bulb weight including the two that had significantly higher bulb weight at Rangpur. The mutants BP2/75/2, BP2/100/2 and BP2/100/12 had significantly higher fresh and dry bulb weights at both locations than the check variety. Finally, bulb yield ha^-1, the ultimate goal of any plant breeding program, was significantly higher in only BP2/75/2 at Rangpur while all the mutants had significantly higher bulb yield at Ishurdi than the check variety.

Keywords: Summer onion, Kharif II season, Bulb yield

Location: BINA sub-station farms, Rangpur and Ishurdi

Start Date: 00-00-2013

End Date: 00-00-2014

Program Area: Variety and Species

Commodity: Onion

Objectives:

To assess genotype-environment interaction of M₇ mutant lines for bulb yield potentials in Kharif II season

Methodology:

The study was conducted during 2013-14 with a view to assess bulb yield potentials of four summer onion mutants in Kharif-II season. Seeds were sown at BINA Head Quarters farm. BARI Piaj-3 was included as a check variety. Seedlings were transplanted finally at Rangpur and Ishurdi sub-station farms, respectively, following RCB design with 3 replications. This study was conducted following RCB design with 3 replications. A unit plot size was 2.0 m × 1.65 m. Plants were spaced at 15 cm within rows of 20 cm apart. Recommended doses of farm yard manure and fertilizers were applied during final land preparation. Data on number of leaves at vegetative stage and bulb diameter were recorded from randomly selected ten competitive plants. Fresh bulb weight was recorded from whole plot at harvest. Dry bulb weight was recorded after 1.5-2 months of harvest and finally converted to yield ha^-1_.

Achievement/Findings:

The mutant BP2/75/2 produced significantly higher bulb yield only at Rangpur while BP2/100/2 and BP2/100/12 including BP2/75/2 produced significantly higher bulb yield at Ishurdi than the check variety, BARI Piaj-3.
